Highway 30 and Thompson Drive Roundabouts

Madison, WI

While with the WIDOT Mark was the lead engineer working in a collaborative effort with The City of Madison, Dane County Highway Department to find solutions to existing traffic congestion and pedestrian and bicycle deficiencies associated with the Highway 30/Thompson Drive (off-ramp) and the Thompson Drive/Commercial Avenue-County Trunk Highway T intersection (on-ramp).

These two intersections serve as an interchange access point to State Hwy 30, which in turn provides direct links to major regional highways, including Interstates 90/94/39 and State Highways 151 and 51. Future residential growth is expected to the east and will add more traffic to these intersections as that growth is realized.  Opened October, 2004.
